This is the deck I have been climbing with post infinite. This is a Black Swan miracle deck that originally used Hit-Monkey but I found sage to be more consistent and that also allows us to use some tempo cards and not relay as much on the turn 6 miracle turn. Deck is a bit tricky to play at first but after practice you will start to understand the playlines and see this deck's potential. I am currently testing Maria Hill for early tempo but you can replace this with any other 1 drop you would like as it does have some anti synergy with strong guy. If you don't have Nocturne you can replace it with something like Red Guardian/Baron Zemo/Polaris/Rogue. If you don't have Cull you can use Kazar but the deck will be weaker. Keep in mind you want a 1 drop down before turn 4 so you can always tempo out Cull even if it means wasting an Elektra or Nico otherwise you won't be able to dump most hands on turn 6 if you still have Cull in your hand. This deck can play for all 3 lanes. Requires strong game knowledge to win games. (Yes it's weak to Leech but you have some static abilities and ongoing cards so the matchup is not unwinnable) Also be prepared for your Sunspot to get hit by Red Guardian and it's not a big deal. It's not uncommon for your turn 6 to be 25+ power. Updated with Shadow King instead of White Widow.
Turn 1: Sunspot/Antman/Maria Hill/Nico for draw 2/Pass
Turn 2: Sunspot/Antman/Maria Hill 2 drop/Pass
Turn 3: Nocturne/Strong Guy
Turn 4: Cull/Strong Guy/Nocturne
Turn 5: Black Swan + 2 drop from Maria Hill if able
Turn 6: Dump your hand (Ideal Turn 6 would be Sage + Strong Guy + Blade/Antman/Nico/Elektra)
